VLMs show task-dependent uncertainty in multimodal evaluation, impacting scoring reliability.

作者 PulseAugur 编辑部 · [3 个来源] ·

A new paper introduces conformal prediction to assess the reliability of vision-language models (VLMs) when used as automated judges for multimodal systems. The research reveals that the uncertainty in VLM evaluations is highly dependent on the specific task, with mathematical reasoning tasks showing significantly wider, less informative prediction intervals compared to image aesthetics. This work also identifies a critical issue termed 'ranking-scoring decoupling,' where VLMs can accurately rank responses but fail to provide reliable absolute scores, highlighting the need for more robust evaluation methods.
